Using a randomized control trial design, this study examines the extent to which a comprehensive college transition program (CCTP) shapes students’ time-use during their first 3 years in college. The CCTP provides comprehensive student-centered support as well as a generous scholarship. We compare students who had access to the CCTP with those who only received the scholarship. Findings indicate that both student groups spent similar amounts of time working for pay, studying, and on social media, and time-use had no differential bearing on college GPA by treatment status. In an exploratory analysis of program components, we find correlational evidence that academic-related interactions with faculty are positively associated with hours spent studying. We consistently find that the strongest predictor of time-use in college is how students spend their time in high school, suggesting that interventions aimed at shaping students’ time-use may be most effective if they are targeted at students’ precollege years.

<b><i>Objectives:</i></b> The aims of this study were: (1) to investigate the effect of colorful semantics (CS) on the morphosyntactic and semantic development of Cypriot-Greek (CG)-speaking children with autism spectrum disorder (ASD) to obtain a better understanding of its role in an augmentative communication (AC) intervention program; (2) to address the paucity of intervention tools geared for CG-speaking children with ASD. <b><i>Participants and Methods:</i></b> The study included 24 boys and 16 girls with ASD, all preschool-aged 4–6 years. All were verbal but with limited production and minimal mean length of utterance. The study followed a randomized control trial design with equally sized experimental and control groups. The experimental group followed a therapeutic program using the AC with a CS protocol, while the control group’s AC intervention did not include the CS protocol. <b><i>Results:</i></b> The use of CS significantly improved the children’s semantic and morphosyntactic development. <b><i>Conclusions:</i></b> The intervention results illustrate the effectiveness of CS in this study; however, generalizability of effectiveness to other similar CG-speaking children with ASD requires further evidence.

Mortality and morbidity due to stroke rank the highest in Indonesia (15.4%), and most types of stroke are ischemic (87%). Inflammation has a role in the pathophysiology of both ischemic stroke and also inhibits acute symptomatic epileptic seizures (3-6%) in the first 7 days after stroke. Statins have been used for the treatment of dyslipidemia in stroke patients. Some studies showed that statins reduced the inflammatory response after a stroke and prevented the recovery of epileptic seizures. This study aimed to determine the differences in lymphocytes, hs-CRP, Electroencephalogram (EEG) with and without Simvastatin in acute ischemic stroke. This research was an experimental study with a double-blind, randomized control trial design consisting of two groups, a group given Simvastatin 20 mg/day, and a group given a placebo for seven days. The difference in lymphocytes, hs-CRP, EEG, and epileptic seizures between the two groups were then analyzed. The sample was 26 people, consisting of 17 (65.4%) males and 9 (34.6%) females with an average age of 59±5.8 years. Chi-Square and Fisher's test showed a significant difference in hs-CRP (p=0.005) and epileptic seizures (p=0.015), but no significant difference in lymphocytes (p=0.336) and EEG (p=0.42) between groups given Simvastatin 20 mg/day and those given placebo. There was a significant difference in hs-CRP and epileptic seizures, but no significant difference in lymphocyte count and EEG between the two groups with and without Simvastatin administration.

This study describes implementation of a clinic-based HIV stigma reduction workshop adapted from work done in Africa to an HIV clinic in Newark, New Jersey. Clinic workers and clients participated in a series of four, three-hour workshops designed to reduce HIV-related stigma. Quantitative data, including the Berger HIV Stigma Scale and the HIV Stigma and Discrimination among Health Facility Staff questionnaire, were collected pre- and post-test over a twoweek period and again at 12 months. Average scores on the Berger Scale fell between baseline and the two-week follow-up, but increased above the baseline level after one year. Average scores on the facility questionnaire were low at baseline and decreased over the study period. Results suggest a need for “booster sessions” to ensure that the intervention sustains efficacy in the long-term. Furthermore, the findings from this preliminary work suggest the need for further research and a larger scale intervention using a randomized control trial design to formally test the intervention’s effectiveness.

Objective: The aim of this study was to determine the effect of lozenges containing kepel fruit (Stelechocarpus burahol) in controlling oral malodor.Methods: This study used crossover randomized control trial design. Each of the 30 research subjects received all three treatments at differenttimes: Kepel, xylitol, and placebo lozenges. The subjects used lozenges in the morning after breakfast and afternoon after lunch. Examinations of oralmalodor were performed thrice: Immediately after waking up, after breakfast, and after lunch. Measured oral odor variables included organolepticscore and H2S, CH3SH, and (CH3)2S levels.Results: Effect of burahol fruit extract lozenges was comparable to that of xylitol gum in reducing the H2S, CH3SH, and (CH3)2S levels and organolepticscores of the subjects.Conclusion: Lozenges containing burahol fruit extract were effective in controlling oral malodor (halitosis).

<p>Patient safety is a system used in hospitals that make nursing care becomes more secure. Systems that can prevent injuries arising from errors in performing the action The accurate implementation of patient identification is one of the components in patient safety. As a nurse, it is crucial to have a good knowledge of patient identification according to hospital’s regulation.The purpose of this research was to know the description of nursing knowledge about identification patients in the inpatient room Private Hospital in Central Indonesia. This study used quantitative descriptive method it cross sectional approach which uses the technique of total sampling. Population in this study was 20 nurses in inpatient Private Hospital in Central Indonesia .This study uses the instrument in the form of a questionnaire that contained 24 questions using a scale Guttman consisting of positive questions and negative questions. This research was conducted in October-November 2017. This study showed by as many as 19 nurses (95%) of the 20 respondents have the level of knowledge of good and 1 nurse (5%) of the 20 respondents have a sufficient level of knowledge. For further research, the researcher recommends a randomized control trial design on a larger number of samples in order to obtain more accurate results. That way, you can see what part of the information in the topic of identifying patients who are still of low value with more objective. In the end, this can be an input for hospital managers to provide training that focuses on improving the knowledge of nurses.</p>

Kadar Hb yang rendah (anemia) merupakan salah satu masalah kesehatan yang sering dialami oleh seorang wanita tidak terkecuali remaja. Remaja putri merupakan salah satu kelompok yang rawan menderita anemia dibandingkan dengan remaja laki-laki karena remaja perempuan setiap bulan mengalami siklus menstruasi dan memiliki kebiasaan makan yang salah. Anemia pada remaja akan berdampak pada penurunan konsentrasi belajar, penurunan kesehatan dan gangguan pertumbuhan sehingga tinggi badan dan berat badan tidak mencapai normal. Kehamilan pada usia remaja juga memberi efek yang panjang yaitu menyebabkan kematian ibu, bayi, atau risiko melahirkan bayi dengan BBLR (Berat Bayi Lahir Rendah), selain itu dapat menyebabkan penurunan antibody sehingga mudah sakit karena terserang infeksi dan dapat menimbulkan kelelahan, badan lemah, penurunan kapasitas/kemampuan atau produktivitas kerja Di Indonesia prevalensi kejadian anemia remaja cukup tinggi mencapai 57,1 %. Penelitian ini bertujuan untuk melihat perbandingan peningkatan kadar Hb antara pemberian Fe kombinasi dengan Vitamin A atau Vitamin C dengan hanya pemberian Fe. Jenis penelitian ini adalah eksperimen dengan rancangan randomized control trial design pretest posttest control group, Jumlah Sampel Sebanyak 105 yang dibagi dalam 3 kelompok perlakuan. Data dianalisis dengan menggunakan uji T dan Anova. Hasil penelitian menunjukkan bahwa pemberian Fe dengan vitamin A memiliki peningkatan rerata Hb yang lebih tinggi dibanding 2 kelompok perlakuan lainnya.
